Complete Rebuild or Bottom End Refresh?
Choose this Complete kit when the repair requires replacement of the crankshaft and connecting rods. If those components remain reusable, compare the Polaris RZR 900 Bottom End Refresh Kit, which supplies bearings, chains, gaskets, and seals without a crankshaft or rods.
The Polaris Crankshaft Bearing Mapping Guide includes separate chart information for the 2011–2012 RZR 900 engine family. Review it for help understanding case codes, rod numbers, crankshaft codes, and bearing positions.
